Hi Jeff and to cc follows:

...

 Attached is all of the information that I have; I haven't been able to try
 this because I'm stuck without a capable ESDI controller. 
Thanks!  But same old hat again,  it's same thing you see on the 
blue planet's website.

There are few ESDI controllers that can do 24MHZ and *MUST* 
able to do up to 4096 cylinders.  Nice thing about all ESDI 
controllers for Peecees, LBA built right in for greater than 528MB!

...
  Looks like you should set for 512 bytes/sector, 83
spt, *hard* sectored. I
 wish I knew that Ultra 12f-24's were so damned rare . . . 
Really?  What about it and why it's bit rare?

And I really beg to anyone on this list to pool their experiences to 
"pull" up the ESDI performance because I'm getting subpar 
performance for a "high" end hd like 1538 with 71 sectors (1518 is 
83 sectors) both hds should have screamed instead of plodded 
along.  About 600KPS out of that 1538, yuk.  I got over 800kps on 
that same controller with a Miniscribe 3180E on that paltry 36 
sectors.

Is there's a controller card that does much better than this Ultrastor 
12F24?!  Oh, I've one computer based on EISA.

Oh, anyone knows of same HDAs that uses SCSI interface board 
in place of ESDI, I want to know what model it shares same HDA 
for each?  1518 and 1538.
